Unbiased identity, purity, and quality verification from Canada’s independent peptide testing laboratory. No manufacturer affiliations — only objective analytical results.
In our database of 1,400+ independently tested samples, only 27% of supplier COAs exactly matched our third-party results. The most common discrepancies are purity over-statement (44%) and identity issues (11%). Our CAD $225–$450 package includes HPLC purity, ESI-MS identity confirmation, and a side-by-side comparison against your supplier’s COA — delivered in 9–11 business days.
Mass spectrometry analysis to verify that the peptide identity matches supplier specifications with no structural errors or modifications.
Comprehensive evaluation of peptide purity, concentration accuracy, and the presence of contaminants or degradation products.
Precise quantification by UV spectroscopy to confirm the labelled concentration falls within acceptable tolerances.
Detailed independent verification report with all analytical results, pass/fail assessment, and recommendations for use.
Many researchers rely on Certificates of Analysis provided by peptide manufacturers. However, independent third-party testing offers critical advantages for ensuring research integrity.
• Incorrect peptide identity (wrong structure or structural errors)
• Lower purity than declared (presence of deletion sequences)
• Inaccurate concentration (labelled vs. actual peptide content)
• Degradation during shipping or storage
• Presence of heavy metals or other contaminants
• Incorrect molecular weight or post-translational modifications

Supplier COAs are produced by the same organization that manufactured the peptide — creating an inherent conflict of interest. Our independent testing has found that 73% of supplier COAs show measurable discrepancies versus third-party results. Independent verification protects your research integrity and regulatory standing.
Simply ship 1–2 mg of your lyophilized peptide along with a copy of the supplier COA to our Toronto facility. Visit our How to Submit Samples page for full shipping instructions.
Our standard package includes ESI-MS identity confirmation, RP-HPLC purity quantification with impurity profiling, and a side-by-side comparison table against the supplier COA. Additional tests (endotoxins, heavy metals, residual solvents) can be added.
CAD $225–$450 per sample for the standard identity + purity package. Volume discounts apply for 5+ samples. Contact us at info@certbiohealth.ca for a formal quote.
Yes. Our COAs are issued by a licensed Canadian analytical laboratory and include all method details, instrument data, and scientist signatures required for Health Canada submissions, research ethics board documentation, and supplier audits.
In our dataset of 1,400+ samples, only 27% of supplier COAs exactly matched our independently determined results. The most common discrepancies are purity over-statement (44%) and identity issues (11%).
Yes. We regularly test peptides sourced from suppliers in China, the US, and Europe. Samples can be shipped to our Toronto laboratory from anywhere in the world.
We provide a detailed failure report explaining where and how the sample deviates from the supplier COA. This documentation can be used to dispute the COA, request a replacement shipment, or switch suppliers. We can also advise on next steps.
The Canadian Peptide Research Alliance requires every vendor applying for CPRA certification to submit a third-party Certificate of Analysis from an accredited laboratory — dated within the last 12 months. Cert Biohealth issues CPRA-compliant COAs that satisfy every document requirement in CPRA’s certification checklist.
